Linux Installation from hard-disk!

While installing linux, you might have seen the option -- installation form hard disk(internal or external), have you ever thought how that is done.
I wonder some of you might be knowing it but its not so popular i guess, though its very useful, saves you from writing DVDs & CDs & your time & money too. I found this 3 months ago.
Of course u require a OS pre-installed in your system.

Click on the link & follow the instruction .

There are two methods listed on the site, depending on your pre-installed system, whether it is windows or linux. If there are more than one linux OS installed in your system, then look for the OS whose grub menu appears at the boot time & apply the methods as mentioned in the site in that OS.

After you did the configurations as given in the site, you have to boot the system & the select the title that you just made while editing /boot/grub/menu.lst or /boot/grub/grub.conf for linux. After some basic configurations, you have to select installation method - choose from Hard-disk & then select the drive Partition & give the path of *.iso image.
I tried it 2 days ago, for me the path was /distro/suse1100.iso . (installing over linux)
after that, its a normal installation.
